Wouldn't the correct solution be a switching transistor and a high ohm resistor?
You know, I can't help myself, it's a coil association thing...aren't we vaping off the primary of an air cored transformer (the secondary is just theoretical in this particular application)
Yes, but that only applies to inductive loads. There's no appreciable "flyback" with an atomizer because there is no appreciable inductance. There is some because any conductor has an amount of inductance, however small, but it's not enough to impact the switch at all.
The problem with tactiles is they typically use a spring steel plate with a very small contact area. That tiny contact area burns easily with higher currents destroying the switch. There's no way to get around that except to use a bigger switch with larger contacts.
Again you drop the current through the switch with a large resistor and pour the primary current through a transistor not the cheap route but you could get all the wattage you want through there.
